Wp 404 Displayed When Trying To Install.

I'm trying to install CS-Cart... however... i get a WP 404 error when trying to get to the install dir.


WordPress is installed in the root dir. CS-Cart is sitting in a sub directory (shop/). I'm thinking WordPress it's not playing friendly with CS-Cart.

if i go to www.mysite.com/shop/... i receive a blank page with the following message:

"CS-Cart is not installed. Please click here to start the installation process: [install]"

However... as stated previously... clicking the link leads me to a WP 404.

Is there something i need to alter in an .htaccess file? Any ideas?
